Final answer:
Jane most likely has Generalized Anxiety Disorder (GAD) because she experiences long-term, nonspecific anxiety. GAD involves persistent worry without a singular cause, unlike PTSD which is a reaction to trauma, or Panic and Phobic Disorders, which have clearer triggers.
Step-by-step explanation:
Jane likely has Generalized Anxiety Disorder (GAD), which is characterized by persistent and excessive worry about various aspects of life without a specific reason, lasting for at least 6 months. GAD is different from other anxiety disorders such as Panic Disorder, where panic attacks occur unexpectedly, or Phobic Disorder, which is associated with a specific fear or object. Unlike Post-Traumatic Stress Disorder (PTSD), where symptoms follow a traumatic event, GAD involves a more generalized, diffuse state of worry.
According to the Anxiety and Depression Institute of America, almost 18 percent of U.S. adults are likely to experience an anxiety disorder within a single year, making it important to distinguish between occasional anxiety and a more severe anxiety disorder. Cognitive theories surrounding GAD suggest that individuals with the disorder often exhibit exaggerated worry and tension, even when there is little or nothing to provoke it.
